Get your taxes done using TurboTax

Then you are trying to use the wrong software.  Did you purchase Home and Business for 2018?  Each tax year has its own software.  You cannot use 2019 software to prepare a 2018 return.  And you cannot use the online program to prepare a 2018 return.  Online is only for 2019.   Are you making the mistake of logging on to online when you should be opening up the downloaded 2018 program on your own computer?  You do not "log on" to desktop software.
